Practical Module development for Prestashop 8

By: Louis AUTHIE

Overview of this book

After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code. This migration brought about significant changes for developers, from routine maintenance to module development. Practical Module Development for PrestaShop 8 is curated to help you explore the system architecture, including migrated and non-migrated controllers, with a concise data structure overview. You’ll understand how hooks enable module customization and optimize the CMS. Through the creation of seven modules, you’ll learn about the structure of modules, hook registration, the creation of front-office controllers, and Symfony back-office controllers. By using Doctrine entities, services, CQRS, grids, and forms, you’ll be guided through the creation of standard, payment and carrier modules. Additionally, you'll customize and override themes to achieve your desired e-commerce store look. By the end of this book, you’ll be well equipped to provide modern solutions with PrestaShop that meet client requirements.

For this practical study, we will focus on how the system initializes and handles a front-page call from the URL request to the controller instantiation.

Let’s do it with a product category page example. When you browse the FO, it’s a product listing page. Indeed, in PrestaShop, a Category is the entity responsible for displaying groups of products.

Initializing a Category FO controller

By default, when URL rewriting is on, the category page URLs are structured like this: https://www.urlofthewebsite.extension/categoryId-name, with categoryId as an integer and name as the slug of the category name...
